>>15943961basically hatoba tsugu is a super cute vtuber from the days of short videos, not streams, fully 3d-rigged from the start, she made very short artsy and/or amateurish style videos with limited if any speaking, focused on very mundane scenarios like buying a fish and setting up a fish tank or brushing her teeth
her extremely simplistic yet super cute design and the nature of the videos built a huge audience of rratfags and she exploded in popularity pretty quickly
then she had a not-kickstarter which raked in like 200k USD
then she was on tv last year
idk about quick, but there's your rundown
